The Verdict
Kong is built for platform engineers and microservices teams, with a focus on api-gateway and service-mesh. osTicket targets small businesses and budget conscious teams and leads with ticket-management and email-piping.
On pricing, Kong is the clear winner for budget-conscious users — starting at $0.05/mo compared to $12/mo for osTicket. That $11.95/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Kong offers broader built-in capabilities (8 features vs 6), while osTicket takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Kong has a slight overall edge — but if completely free self-hosted version matters most to you, osTicket may still be the right call.
